Abstract: PURPOSE: To accelerate selective chlorination reaction and oxychlorination reaction by depositing a catalyst material on a monolithic carrier which has lots of passages arranged parallel to the axial line in the longitudinal axial direction with both ends open and which has the length corresponding to the diameter of the passages. CONSTITUTION: This catalyst for chlorination of hydrocarbons is produced by carrying a catalyst material directly or through a coating layer which accelerates the catalytic effect on a monolithic carrier. The carrier has passages arranged parallel to the axial line in the longitudinal direction with both ends open and has the length at least corresponding to the diameter of the passages. By filling a tubular reactor with the catalyst above described, chlorinated hydrocarbons can be produced by the selective chlorination and/or oxychlorination reaction. In this method, the catalyst is preferably arranged in plural blocks succeeding to each other in the tube of the tubular reactor.

Abstract: PROBLEM TO BE SOLVED: To improve the dispersibility in a lipophilic medium and a hydrophilic medium by treating titanium dioxide with at least one ammonium functional silane. SOLUTION: A surface-modified titanium dioxide is produced as follows: A solution of a silane or a silane mixture is sprayed on a pyrogenically prepared titanium dioxide, as necessary, in the presence of water or a dilute acid in a mixing unit for carrying out vigorous mixing. The resultant mixture is further stirred for about 10-30 min and then heated at 100-400 deg.C for 0.5-6 h. The resultant titanium dioxide has the following physicochemical properties: 15-100 m2/g BET specific surface area, 150-700 g/L bulk density, 2.5-8.5 value of pH, 0.1-2.0 mass % loss on drying, 0.3-13.0 mass % ignition loss, 0.3-12.0 mass % carbon content and 0-50 mass % wettability with methanol.

Abstract: PROBLEM TO BE SOLVED: To provide a layer on a substrate having high mechanical stability and free from cracks. SOLUTION: This layer is obtained by heat-treating an aqueous dispersion coated on a substrate where the dispersion contains a silicon-titanium mixed oxide powder produced by flame hydrolysis. The layer is formed by the steps of coating the dispersion containing a silicon-titanium mixed oxide powder and sintering the coating by a heat treatment. The layer can be applied to a material with extremely low expansion percentage. COPYRIGHT: (C)2003,JPO
